If the infrastructure inTTL is a much improved model..more railroads, improved harbor facilities, better roads, increased economic activity in the cities, etc...and this takes place in the 1850's..and beyond...does this postpone, or eliminate entirely the Civil War? Someone mentioned that the new Mexican population would be closer politically to the North than the South. WOuld the South just accept the gradual elimination of slavery and count on low cost labor from further south being added to their former slaves, while shifting from cotton to a more diversified economy? Or am I dreaming...that the Southern planters would actually be smart enough to do that?
